Generation and characterization of a Meflin-CreER(T2) transgenic line for lineage tracing in white adipose tissue

Meflin (Islr) expression has gained attention as a marker for mesenchymal stem cells, but its function remains largely unexplored. Here, we report the generation of Meflin-CreER(T2) mice with CreER(T2) inserted under the Meflin gene promoter to label Meflin-expressing cells genetically, thereby enab...

Sumario:Meflin (Islr) expression has gained attention as a marker for mesenchymal stem cells, but its function remains largely unexplored. Here, we report the generation of Meflin-CreER(T2) mice with CreER(T2) inserted under the Meflin gene promoter to label Meflin-expressing cells genetically, thereby enabling their lineages to be traced. We found that in adult mice, Meflin-expressing lineage cells were present in adipose tissue stroma and had differentiated into mature adipocytes. These cells constituted Crown-like structures in the adipose tissue of mice after high-fat diet loading. Cold stimulation led to the differentiation of Meflin-expressing lineage cells into beige adipocytes. Thus, the Meflin-CreER(T2) mouse line is a useful new tool for visualizing and tracking the lineage of Meflin-expressing cells.
